The different ways to induce a current in a coil are as follows:
- If a coil is moved rapidly between the two poles of a horseshoe magnet, then an electric current is induced in the coil.
- If a magnet is moved relative to a coil, an electric current is induced.
- By keeping it stationary and rotating a magnet inside it, the current in the coil can be induced.
- The current may be caused by constantly altering the current in ‘another coil’ held near it in a coil.
Faraday’s Law of Induction
Michael Faraday’s famous law of electromagnetic induction states: “A voltage is induced in a circuit whenever relative motion exists between a conductor and a magnetic field and that the magnitude of this voltage is proportional to the rate of change of the flux”. Faraday law is one of the most basic and important laws of electromagnetism. This law finds its application in most electrical machines, industries, the medical field, etc.
